Cobalt-platinum heterometallic clusters containing N-heterocyclic carbene ligands

Publication date: 1 November 2017 Source:Journal of Organometallic Chemistry, Volumes 849–850 Author(s): Bo Yang Chor, Wei Xiang Koh, Rakesh Ganguly, Yongxin Li, Luwei Chen, Robert Raja, Weng Kee Leong The heteronuclear cobalt-platinum cluster [Co2Pt2(IPr)2(μ 2-CO)4(CO)4] can be obtained from the [Pt(IPr)] fragment through an addition reaction with [Co2(CO)8], and with subsequent cluster fragmentation, with [Co4(CO)12] and [Co3(μ 3-CH)(CO)9]; the latter reaction with the methylidyne cluster also afforded another cobalt-platinum cluster [Co4Pt2(μ6-C)(IPr)2(μ 2-CO)5(CO)6]. These are the first examples of Co-Pt heteronuclear clusters containing NHC ligands. Graphical abstract
